BENJAMIN COPLIN SEATON. OF s'r. Louis, nissourn;

; WHEEL.

To all whom it may concern: Be it known that I, BENJAMIN CoPLIN SEATON, a citizen of the United States, residing at St. Louis,

- Missouri, have invented a certain new and useful Improvement in Wheels, of which the following is a full, clear, and. exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a cross sectional view of a wheel provided with a rim constructed accordance with my invention; Fig. 2 is a detail perspective view-of aportion of the spring fastening device; Fig. 3 is a detailperspeo tive view of the ball member; and Fig. 4 is a perspective View of the cap.

This. invention relates to wheels andparticularly to the type otwheel shown in my United States Patent No. 814,737, dated March 13, 1906.

.'Ilie-wheelshown in HQ -prior patent above referred to was provided with a tire consisting ofan inner rim attached to the telly of the wheel, an outer rim, and transversely arranged tension springs connected to the outer and inner rims.

One object of my invention is to provide novel means for connecting the tension springs to the outer and inner rims wherebysaid springs can be inserted easily and all danger of their being accidentally displaced will be obviated.

Another object of my invention is to provide means for varying the tension of the springs, and still another object is to provide means for preventing dust and" v ball and socket jointformed by the members 9 and 10,

dirt from entering the points at which the springs'are connected to the rims.

Referring. to the drawings which represent the preierred form of'my invention, 1. designates the wooden folly of a wheel having arms or projections 2 secured thereto by bolts 3, the arms being arranged alternately on opposite sides of the telly. The outer rim 4 which carries the rubber tread 5 has arms or projectionsfi secured thereto by bolts 7 and these arms arealso ar-- erating .with the arms 2 at the righthand side of the telly, as shown in Fig. 1, and those at the righthand side of the outer rim cooperating with the arms at the lefthand side oithe felly.

Preferably, and as herein shown, the outerrim is made up of two angles, and the bolts 7 which connect the arms 6 to the outer rim extend through the rubber tread and thus hold it securely in position. Transversely extending tension springs 8 are arranged between the cooperating arms 2 and 6 and these springs are retained-in operative position in a novel manner. Each oi the arms 2. and 6 is provided at its outer end with a socket member 9 which receives a ball member 10, thus forming a universal joint.

Patented July so, 190%;

Fastening devices 11 having flared e nd's l2 which extend inside of the coils at the outer ends of the springs, project through the bores 13 in the ball mem bers 10, each of said fastening devices being provided with a tapered head 14 that is adapted to engage notches 15 in the .ball member 10 and thereby securely retain said fastening device in place and also permit the same to have a universal movement. Each of the ball members 10 is provided with diametrically op posed slots16 extending from its central bore andpreferably with. a plurality of pairs of notches or recesses to receive the tapered head 14 of the fastening device, said pairs of notches being diametrically op;

posed and being of different depth, as shown in 3 in which the notches 15" are oi less depth than the notches 15. I haye herein shown the ball member as being provided with only two sets of such notches but it should beunderstood that the number of notches with which the ball member is providedis immaterial. In assembling the parts, the devices 11 are first connected to the springs and are then connected'to the ball members by inserting the headsl4 of said devices through the slots 16 and then turning said devices 'until their heads rest in one of the pair of notches 15 whereby said devices will be securely retained -po-.

sition, the shanks of the devices 11 being of approiti mately the same size as the bores of the ball members When it 'is-desired' to vary the-tension of'one of the springs, either or both of the devices 11 can be turned until their heads 14 rest irinotches 15 of,different depth. To preventdust and dirtfrom entering-the and also insure keeping this joint thoroughlylubricated, caps 17 are connected to the outer ends of the socket members 9 as shown in'Fig. 1, and some lubri- "cant ispacked in around the ball member.- The caps 1. A wheel comprising an outer rim and an inner rim provided with cooperating projections, tension springs arranged transversely betwcen said projections, rockable 7 members mounted in said projections. and adjustable devices for connecting said springs to sag rockable members;

substantially as described. 7

2. A wheel comprising an outer ri and an inner rim provided with cooperating projections, ball and socket members carried by said projections, tension springs arranged between said projections, and fastening devices en-g gaging the springs and removably connected to said ball members substantially as described.

' said means consisting and are provided with heads that are inserted through 3. A wheel comprising an outer rim and an inner-rim provided with coiiperating projections, ball and socket duembers carried by said projections, each of said ball members being provided with a. bore and a recess, springs arranged between said projections, and fastening devices for said springs which project through the bores in the Ig'all members and are provided with means for engagingthe recesses in said members; substantially as described.

4. A wheel comprising an outer rim and an inne'rrim provided with eofipcratine, projections which carry ball members, said members being, provided with bores and diametrically opposed slots extending from said bores, springs arrangedbetween said projections, and means for removahly connecting said springs to said ballmembers, of devices which engage the springs the diametrically opposed slots in-the bail member and thenturned to carry said heads out of alinement with said slots substantially as described 5. A wheel comprising an inner rim and an outer rim provided with cooperating projections, ball members car v ried by said projections and provided with a plurality oi! notches of different depths, springs arranged between said caps covering said ballmembers; substantially as 'described. I

7. A wheel comprising an outer rim nnd'an inner rim provided with coiiperating projections, bail and socket members carried by said projections, transversely extending springs connected to said ball members, removable caps covering the ends of the socket members, and means on said caps tor-preventing them from being displaccd;

substantially as described.

In testimony whereof, I hereunto aifix my signature, in, the presence of two witnesses, this 31st day of May 1906.
